Hello,

Right.  So in particular, docker wants to do something like:

bindpath=`grep freezer /proc/self/mountinfo | tail -n 1 | awk '{ print $4 }'`
mountpoint=`grep freezer /proc/self/mountinfo | tail -n 1 | awk '{ print $5 }'`
mycg=`awk -F: '/freezer/ { print $3 }' /proc/self/cgroup`
cat ${mountpoint}/${bindpath}/${mycg}/cgroup.procs

and see its own task.

Can you please make the example more concrete?  e.g. Use actual paths
and show what they show now vs. what they should.

Thanks.
